South America’s wide range of habitats support a tremendous diversity of plants and animals, including more than 400 species of larger mammals—those the size of a guinea pig or bigger. Many are truly iconic: Jaguar, Puma, Ocelot and numerous other beautiful cats; the fantastic Maned Wolf; the incomparable Giant Anteater; and an incredible variety of extraordinary primates. This groundbreaking guide provides detailed coverage of these and many other wonderful mammals, including porcupines and peccaries; squirrels, sloths, skunks and seals; opossums, olingos and otters; armadillos, agoutis and Andean Bear; and viscachas and Vicuña—not to mention tapirs and river and estuarine dolphins. The species accounts include a description of key features and information on subspecies, comparisons with similar species that overlap in range, details of the habitats in which the species occurs, a summary of its distribution in South America and information on its conservation status. Each species is illustrated with carefully selected photos, or artwork where suitable photos were not available.
